Me again. I have just fitted a new stem to this damn omega. The quick set calander function works fine. Setting the hands is working fine.

But when i come to winding it up it starts to slip as if teeth are missing from clutch or winding pinnion and there are no teeth missing. Ive attached pics incase there is something wrong with the set up that i cannot see.

Any advice suggestions would be a help.

cheers

Just a thought but thinking laterally, could it possibly be an issue with the mainspring slipping? I mean maybe if the barrel arbor hook hasn’t quite engaged with the mainspring hole this may resemble a simple effect.

dose it have an autmatic  spring??   if so,  theres your problem.  i have an omega speedmaster, 1970 that slips just like that..  here is my opinion --main spring is broken or the spring ( on ether end) "sliped the hook".  vin

Hi

thanks guys yes it does have auto spring i was hoping not to have to strip it .

Thanks for your time and help

can any one recommend a video to watch about this or some diagrams.

surely mark must have a video on this?

Just moved the auto wind on the back left and then right and it is winding in both directions. So can it still be the mainspring?

cheers

Hi Gary,
In my opinion it could still be the mainspring, yes. I’m sure I’ve seen a video that Mark made on the subject. If you’ve not done one before, do take extra care as mainsprings flying out of the barrel could cause injury so eye protection is important before starting. If you haven’t replaced the mainspring yet, it’s probably just as well to purchase a new one. Then you can just push it into the barrel generally shim coloured side up (for right hand wind).

Good luck,
Adam

Forgive  me if my terminology  is off..slipping could  only be but so many things.provided all your  gear teeth are good  and properly  engaged.it could  be your  mainspring.  Even  if it is broken  the watch could  run.I have seen it happen friction  and pressure  are often enough  to hold the spring in place up the a certain  amount  of tension..and then slipping occurs. You could  also have a cracked  barrel. Inspection is in order

Hi

I have just wound it fully using the auto bridge.(the bit that moves to auto wind it). I will check tomorrow and see if its still running. 

If not I will replace the spring. Are cousins own make good? There half the price of omega

Cheers

Cousins UK sells Generale Ressorts. They make springs for the entire Swiss industry since 1857.

Do you mean slipping as in you feel tension build then suddenly release which would point to the slipping spring which may be weakened or as in you feel like the teeth of the winding pinion are catching and disengaging?

This later would point to a meshing problem due to wear on winding pinion/crown wheel teeth or pivots or an assembly problem.

Hi

Wound it up last night by the auto winder and its still going and its the correct time. I have watched the clutch and crown gear and i cannot see a slipping movement. But i think it may be the crown gear so i will have to strip it and see.

If it is i will post pics tomorrow.

Thanks for all the advice and sugestions its much appreciated.

cheers

    • Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?
    • Never and others. Yes like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross  
    • Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.
    • Get someone local to tig it ,very easy fix and should only take a few minutes so probably wouldn’t cost much ,or failing that get it very clean and silver solder it. Dell
    • Hi, The winding pin is not split, well that's how it was when I obtained the watch. The movement is front-loaded and here's a picture of where the case screws are fitted. The face picture is before I dismantled it. Quick update.  I've always had a nylon ring sitting in the parts try that I wasn't sure where it went and left it to the last thing as I know it must be part of the case assembly. Anyway, looking at the picture in my last post you can see, just under the winding stem, a white-looking object, this is the nylon ring 🤭 So, I had to remove the dial again and replace the ring. Once this was all back together I placed the movement in the case and realized my initial problem maybe is not a problem as it looks like I can screw the movement back in the case and then place the hands as the dial is nearly flush with the outside of the case anyway so I'll be able to check for alignment. if all is good then just fit the crystal and bezel 🤔 I can't think of any issues with this approach but please comment if you think I've not thought of something. Another lesson learned as well. Take more pictures not just of the movement parts and location 😅
